1)should the lineup of the person matter...example-vernon wells... blue jays lose delgado and now ppl r saying that wells wont do aswell.
Yes it matters for sure. It modifies AVG and HR a little bit but most importantly it effects R and RBI which is 40% of a players value.
should the team matter? example jason bay-rookie of the year but pitt lacks offense and lost kendell
Yes team matters a lot. Just like lineup it modifies R/RBI which is 40% of your numbers. It also strongly modifies SB based on how much the manager likes to run and the home stadium can modify AVG and HR. This is one of the biggest factors out there.
should his emotions matter? example-jose guillen and milton bradly
Not at all. If anyone is staying away from these players because of their attitude they are foolish. The stats speak for themselves here.
should injuries of last year matter? example Maglio Ordonez
Yes for sure. A player coming off of an injury generally play worse than they normally would. The specifics of the injury make a big difference though. If nothing else a player coming off an injury is always a bigger risk than one that isn't. Generally speaking you get them cheaper though so they offer a bigger reward as well.
